archos dvr station question

[Baba booey]

I bought a dock off someone that they used for a 404 and I can't use my 504 on it for obvious reasons. Do the 404, 504, and 604 use separate docks? If not, I'm probably gunna have to put it on ebay.

EDIT:it was the saddles...I got it working. Never mind.

I think 504 and on it's the same dock. I also have a question about the USB sych cable are the 504 and 604 the same usb sych cable?
